DynamicQueryEngineBaseCreateSubqueryConnectionClausesUpdate Method
Produces a set of WHERE Clauses to use in the UPDATE queries which have filters spanning multiple entities. It produces one clause if it finds the updateTable on the PK side and then stops and it produces n clauses if it finds updateTable on the FK side of n relations in relationsToWalk. If the updateTable is on the PK side, it produces a clause: updatedTableAlias.PKField1 = updateTable.PKField1 AND... (for each field in the PK 1 clause) If the updateTable is on the FK side, it produces updatedTableAlias.Field1 = relatedEntityTable.Field1 AND ... clauses for each relation the table of the persistence info is in.
